hair loss and scalp sensitivity

The fragrance was so strong, and it was not good for my scalp, causing some light hairloss from the sensitivity. I stopped before it got too bad, and it was temporary, but it doesn’t seem good for sensitive skin.

Caused dramatic hair loss

I bought this product because I noticed I was losing more hair than normal and was hoping to improve my thinning hair. This product did the exact opposite, 2 weeks of using it consistently and I experienced a huge amount of hair loss, to the point that I felt like I was balding all over my head, and my scalp felt like it was crawling. More significantly I developed daily headaches which persisted for several days even after I stopped using the product. The entire experience was traumatizing. If you have sensitive skin or experience these symptoms I'd stop using it immediately.

This one is still out for discussion.

I have been applying this one to my scalp for about 3 and a half weeks. At first I thought you applied to your hair but I was wrong. This product is supposed to help you grow healthy hair.

Changed the formula DONT BUY in USA.

They took out aminexil from the USA formula. It’s the only scientifically proven active ingredient that works in it. They posted no where on their website that the ingredients changed. Did you know that if you stop using it, that your hair will start falling out? So everyone using this serum that receives a new formula (which is again not advertised) will have hair fall. Under the FDA L’Oréal has to list all of its ingredients, take a look, it’s no longer in the product and no new formula is advertised. I want a full refund, there is nothing on the website that advertises this change. The new formula is also watery and not of serum consistency.

[This review was collected as part of a promotion.] I haven’t been using long enough to see results yet, but I love the scent and the serum absorbs well into my scalp.

So far, so good !

I’ve only been using this for about two weeks & I already have new growth. I only use in the front and along my part - places where I have fallout . I use less than the directions actually say to use however I’m still impressed. I’m looking forward to continuing this routine. While some state the smell is too strong, it’s not for me and actually pleasant. Def worth the money so far and I wish I had started sooner. If you’re on the fence, TREAT yourself and for a (in the long run) small price , you’ll have the hair you deserve.

IT’S AMAZINGLY EFFECTIVE!!

THIS SERUM WORKS!! I’m on my pre- menopausal stage of my womanhood, a chemical hair treatment that was recently done weakened my hair follicles, and I have Hashimoto’s disease in which my thyroxine level is severely low. Put this all together and my hair would be falling - off anywhere esp when combing it and during shower time. It can be embarrassing sometimes that I would catch them fall over my patients while giving care. But this serum is able to control more hair falls as long as you use it regularly. It was so evident after showering. The amount of fallen hair significantly decreased when I started using it. It’s just that it’s so expensive. It’s the only serum for hair falls that worked among all the ones I tried.

It has a very pleasant fresh smell which is not overpowering and and the smell doesn't cause any

Stronger, healthier hair with less fall

This serum has been a game changer for my hair. After a few weeks of use, I noticed significantly less breakage and hair fall, especially when brushing. It absorbs quickly without leaving a greasy feeling and has a pleasant, light scent. My scalp feels soothed and balanced, and my hair looks stronger and shinier from root to tip. A little goes a long way, making the bottle last longer than expected. I love that it works as both a strengthening treatment and a daily scalp care product.
